CS470/CS471 Compact Bubbler System

7.1 DIP Switch Settings

The default DIP switch settings are shown in TABLE 7-1. The default settings

support SDI-12 communications, which is the communication method typically

used by our dataloggers. The DIP switch settings need to be changed if using 4

to 20 mA communications (see Appendix C, 4 to 20 mA Operation).

7.2 Installation/Water Depth Considerations

The CS470/CS471 and bubble chamber should be installed so that the tubing

has a continuous drop from the CS470/CS471 towards the bubble chamber.

Otherwise, moisture can collect in a hallow and potentially block the tubing

with the formation of drops.

The bubble chamber must be installed below the water at a fixed depth. The

maximum water depth is determined by the maximum tube length, which is

15.24 m (50 ft).
